Before beginning, wear gloves and safety goggles as working with broken glass could cause injuries.

Remove any broken glass pieces that remain. This is best done using a pair of pliers, however, a flathead screwdriver may be effective in a pinch. After that, use a wood chisel or putty knife remove the remaining old putty from the frame and sash. Be careful to not scratch the window sash. Work slowly and carefully. It is recommended to do this using a sturdy ladder instead of the ground, and to have someone stand below the sash in order to help hold it steady.

Once you've removed all the old putty, prepare the window frame for the new pane. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of width and height. These measurements can be taken to an hardware or home centers store to get cut a piece of stock glass to the right size. You can cut the glass yourself if you possess the appropriate tools.

After installing the new glass Apply a small amount of caulking to the edge. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points should not be so tight that they create friction between the frame and sash, but they also should not be too loose.

Before applying the putty to the surface, knead thoroughly until it is smooth and free of lumps. Roll it into pencil-sized strips. The first strip should be glued to the frame's corner. Work from one corner to the next to ensure it's even and smooth.

Glazier's Points

The glazier’s points are small triangular pieces of steel that allow glass to be secured into the window frame without causing damage to the delicate surface. It's simple to learn how to use this hidden tool and you can save money on the cost of a professional installation.

After the old putty and glazier's points are removed Clean the frame thoroughly using a utility knife to remove any remaining traces. If needed, lightly sand the wood in the grooves of the rabbet to smooth out rough spots. If you do sand your wood, be sure to protect it with painter's tack to avoid accidental damage.

Take the dimensions of the frame and write down accurate measurements. Take these dimensions to a hardware store or a home center, and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane in the frame and push firmly using your hands. Then, you can use the point of your chisel or the back end of the putty knife to pierce the glazier's facets, as illustrated in Figure 11. When you're done, they should be level with the top edge of the pane. the shoulders of the points should be below the lip of the rabbet groove.

Apply a small amount of glazing compound on the edges of the glass that has been made and into the rabbet grooves, to seal and protect them. Allow this to dry and cure fully.

Once the glazing compound has dried it's time to put in the new window sash. First, saturate the wood with a thick coat of Linseed oil. This will prevent the new putty from sucking up the moisture and drying out and cracking over time. Use a brush to apply this coat, or the tip of the blade. Then use the chisel on the back of the putty tool or the back of the handle to gently hammer the new sash or glazier's point into grooves of the rabbet. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball hit, a rock thrown in error, or a fallen tree could result in a broken or cracked window. Most windows can be replaced easily by installing a new piece. The glass is held in place by a small metal clip, also known as the glazier's point, and putty. This compound is also known as glazing compound. Before installing a replacement pane, first remove the old one and clean up the area using a rag and a pull-type paint scraper or the wood chisel. Wear safety glasses and gloves while working. You'll require a heat gun if the window is glued to the frame.

If you're planning to install the original sash, gently remove any pieces of molding that hold the old pane in place. Then, sand the sash to ensure it's smooth and ready to be re-caulked. After the sash has been re-installed then, apply a new silicone caulk to the glass to ensure that it won't leak or discolor over time.

Remove the glazing points from the rabbets. These are the grooves in the sash, which is where the glass is located. If they're hard to cut, place the hand tool, such as a heatgun over them to allow them to soften before. If you're using a heat gun, be careful not to scratch the railings or sash by using the tool too tightly.

Create the bed for your new pane after removing the old glaze and putty. Roll a rope with glazing compound between your fingers and make it around 1/2 inch thick. Place it into the rabbets, where the glass will be put. It's important that the glass sits on the putty on each side So if you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane has cracked, you can apply the silicone caulk or Replace Window pane glass glue based on solvents to seal the crack prior to pressing it in the sash. If the crack is not sealed, you will require putty to keep the water out. After the putty has dried, wipe the oily film off the glass and allow it to dry completely before you paint.

Paint

Once you're ready to begin, begin by removing the old window pane by prying out the metal glazing points that are connected to it. These are essentially small metal triangles that act as "nails" that hold the window in place in the wood frame. They are submerged beneath a layer of glazing putty that hardens into a solid, molded wedge which holds the window in place and hides the edges.

After you have removed the old pane removed, clean up the surrounding frame and wood. Scrape off any paint that has been used and sand the rabbet grooves in which the glazing points were. These should be sanded to bare wood, to allow you to paint them the same shade as the rest of the frame. After sanding, apply a coat of flax oil on the bare wood to prolong its life.

Then, you need to measure the size of the window opening. You'll need to take horizontal and vertical measurements of the entire opening as well as the thickness of the old pane. To get the exact size of the new pane subtract 1/8 inch from both measurements. This will also allow for expansion and contraction of the glass during seasonal changes. Take these dimensions to a hardware or home improvement store, and they will have the glass cut for you.

Now, it's time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides. Use a putty knife to smear the putty evenly, making sure that there isn't an excessive amount of excess putty in the corners and along the edges. When the putty dries, it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
